But his fears were allayed by the demonstration he received from these companies, where he saw the advertisements were stuck with stick-ons and pulled out smoothly.

Besides, the opportunity to earn Rs. 20,000 a month for three months was too good to miss, felt the 60-year-old Khurana.

Raghu Khanna, Managing Director, Delhi-based Cashurdrive, which set shop in 2009, says: "Dilemmas like those of Vaid and Khurana are commonplace. But the concept is fast gaining ground among private car owners.".

Most important is the route you take on a daily basis and the average area you cover while travelling.

"Demographic information is important, as brand managers often pick the cars based on the profile of the driver," says Karan Bhardwaj, co-founder, Mumbai-based Adometer.

The target audience's age group is linked to that of the driver. Say, Adidas wants to advertise; it will define the required driver's profile to the car advertising company, such that it matches their target audience.
